REFRIGERATINGAPPARATUS FOR CARS, 80C.

SPECIFICATION forming part of Letters Patent No. 294,209, dated February 26, 1884.

Application filed October 22, 1883.

To all whom it may concern Be it known that 1, WILLIAM H. DOUGHTY, a citizen of the United States, and a resident of NewYork, in the countyof New York and State of New York, have invented certain newand useful Improvements in Refrigerating Apparatus, of which the following is a specification.

My invention relates to a refrigerating apparatus in which a fan or blower is employed to produce a current of air, which, after pass ing through an ice-chamber, is carried through a provision-chamber, and again conducted through the ice-chamber, in order to reduce its temperature so that the same volume of air may be used over again for refrigerating purposes. I

- The invention consists, essentially, in a novel construction and combination of devices whereby a series of refrigeratingchambers may be connected with each other, so as to be operated by a single fan, and whereby two or more of such refrigcrating-chambers may receive the benefit of said current of air, while provision is made for affording access to any desired one of such chambers without interfering with any of the others.

The invention is applicable to either stationary refrigerating chambers where provisions are stored, or to railway-cars where provisions are transported from place to place, or to barges or other vessels used for purposes of transportation.

In the accompanying drawings, Figure 1 is a longitudinal vertical sectional view of a series of chambers or compartments embodying my improvements. Fig. 2 is a longitudinal sectional view, showing the application of my invention to railway-cars.

In Fig. 1, A represents a chamber or compartment, in the front end of which is an icechamber, B, and in the upper front corner of which is afan or blower, G, of any suitable description. The fan-chamber communicates with the upper end of the ice-chamber B, and the lower portion of said ice-chamber B com.- municates with the interior of the chamber A.

In the top of the chamber A is a flue, F, provided with valves f f connected to each other by a rod, 6, and another flue, H, pro- A to the flue F, thence down through the ice- (No model.)

struction to the first-nan1ed, except that they are not provided with fans or blowers, and they adjoin each other, so that the flues F and II of each chamber communicate with the corresponding flues in the adjoining chambers.

It will be seen that the arrangement above described may be extended indefinitely, so as to include any desired number of compartments or chambers.

NVhen all the chambers or compartments are closed and in use, the air-ciurent generated by the blower passes through the icechamber B, thence through the compartment chamber B through the compartment A to the flue F, and so on to the end of the flue F, from whence it passes to the flue H and returns to the fan-chamber. By this arrangement the same'volumc of air is used over and over again for refrigerating purposes.

\Vhen access is desired to any one of the compartnients without interfering with any'of the others, the valvesff are arranged so as to close communication between it andthe others, and thus prevent the admission of warm air to either of the flues, and thence to the compartments, while the valves h are turned so as to close communication with one flue and open communication with the other.

Referring to Fig. 2, J J J represent three cars of a railway-train, each of which is provided withan ice-chamber, flues, and valves or dampers similar to those above described, and communicating with a fan or blower located at any suitable point.

In order to provide for communication between the cars, flexible connections of any suitable form are provided. As here shown they consist of bellows-like tubes or flues K, which allow for the passage of atrain around a curve I together in pairs, whereby the opening of one and for any differences which may exist in the passage closes another, and a circulation can height of different cars. be conveniently obtained in either or all of What I claim as new, and desire to secureby the compartments, as set forth.
